Abstract：Solar photovoltaic/thermal system(PV/T)is an efficient energy technology capable of providing both electricity and heat simultaneously,and it has broad application prospects in the field of renewable energy.However,the existing PV/T systems still have deficiencies in terms of thinness,flexibility and thermal management,which limits their application in portable energy devices.To solve this problem,a thin and semi-flexible PV/T absorber based on thin-film monocrystalline silicon cells is proposed,and its thermoelectric performance under different environmental conditions is systematically studied through experimental methods.The results show that under the typical climatic conditions in Shanghai with a water flow rate set at 0.06 kg/s,the daily average photoelectric efficiency and photothermal efficiency of this absorber reach 13.89%and 27.75%,respectively,demonstrating good photoelectric conversion and thermal energy collection capabilities.Compared with other PV/T systems,this absorber features a simple structure,portability and high power density,effectively meeting the demands for efficient and portable energy in scenarios such as wilderness survival and outdoor activities.
